We know HTC is trying to master updating its devices to Android 2.3 Gingerbread and it looks like the carrier variants are not left out at all. The T-Mobile G2 — the carrier variant of the HTC Desire Z — was rumored to get Gingerbread this summer and a test ROM has been leaked to prove it.

Those of you who own a T-Mobile G2 have several reasons to be excited about this: first of all, an official “stock” ROM is definitely on its way — and probably hitting soon — and second, with the test ROM out, you can all hope someone cracks the nut, irons out the glitches and makes it available sooner in the shape of a custom ROM.
